我想吸引社区分享我们的容忍Nutanix驱动的VMware Horizo​​n VDI设计和体系结构，希望它能打开一些对话框，并可能在其他客户进行这项工作时为其他客户提供帮助。



我将不得不分享一些背景信息而退出设计。我为准政府机场管理局工作，该机构雇用了一个相对较小的团队，该团队由六名专用IT员工组成。由于我们正在为机场设计解决方案，因此绝对必须容忍和高可用性。我们的一些台式机是任务至关重要的生命安全机器。该集群中的桌面系统支持我们的消防部门，警察局和机场运营。我们的数据中心每天都在校园里被数百架蜂群以低海拔飞行，我们花了很多时间来设计基础设施。我们最后一次希望在事件中出现桌面的问题。我们永远不会关闭，并且每年365天进行操作 - 我们尝试设计东西，因此我们不会在午夜的圣诞节前夕工作。



经过几次迭代后，我们降落在三个Nutanix服务器的两个单独的群集上。这两个集群中的每一个都有其自己的vCenter服务器（VCSA），两个VMware Horizo​​n视图连接服务器（内部和外部），文件服务器和VMware View Composer Server。我们正在利用非固定的链接克隆。用户有权获得有关应用程序需求和业务部门的几个池中的一个。所有池都在运行Windows 10 LTSB。我们正在使用Liquidware的个人资料Unity与“正常”组策略设置一起管理配置文件，以改善桌面体验。DFS复制和名称空间位于两个文件服务器之间，配置文件数据存储在此DFS空间中。我们利用VMware Cloud Pod功能在两个群集中获得全局权利。负载平衡器可以帮助我们在两个群集之间路由桌面请求。



到目前为止，这对我们来说是一个很棒的建筑。我们可以在一天中间运行更新到vCenter，而Horizo​​n View组件则不受影响另一个集群的生产可用性的风险。我们在复制基本图像方面面临一些挑战 - 今天，我们使用VMware内容库来复制两个群集之间的基础，这确实有效，但由于vCenter强加的流量的取消优先级别，大约需要20分钟才能复制基础。图像从一个群集变为另一个集群。重新组合必须进行两次（按“每个群集”为基础），但这对Nutanix来说并不重要，因为它们是如此之快。



我欢迎有关如何以更有效的方式将基本图像从另一侧转到另一侧的任何建议。当我们使用Nutanix Metro在群集上复制VM时，我们面临一些挑战，因为我们需要从两个单独的vCenters中从单个基本图像创建快照，而VMware不喜欢这样。无论如何，我希望当他人思考在Nutanix上的视野部署时，这对他们有所帮助。

\nI would be remiss to dive into the design without sharing some background information. I work for a quasi-governmental airport authority that employs a relatively small team of six dedicated IT staff. Because we are designing a solution for an airport, fault tolerance and high availability is an absolute must. Some of our desktops are mission critical, life safety machines. The desktop systems in this cluster support our fire department, police department and airport operations. With our datacenters on a campus surrounded daily by hundreds of swarming planes flying at low altitudes, we spend a lot of time designing our infrastructure. The last time we want problems presenting a desktop would be during an incident. We never close, and operations occur 24\/7 365 days a year \u2013 we try to design things so we are not called in to work on Christmas Eve at midnight.

\n

\nAfter a few iterations, we landed on standing up two separate clusters of three Nutanix servers. Each of these two clusters has its own vCenter server (VCSA), two VMware Horizon View Connection Servers (internal and external), a file server and a VMware View Composer server. We are utilizing non-persistent Linked Clones. Users are entitled to one of a several pools contingent on application needs and business unit. All pools are running Windows 10 LTSB. We are using Liquidware\u2019s Profile Unity to manage the profiles in conjunction with the \u201cnormal\u201d Group Policy settings to improve the desktop experience. DFS replication and namespace is in place between the two file servers and profile data is stored within this DFS space. We utilize the VMware Cloud Pod features for a Global Entitlement across the two clusters. A load balancer assists us in routing desktop requests between the two clusters.

\n

\nThis has been a great architecture for us so far. We can run updates to vCenter, and the Horizon View components in the middle of the day without the risk of affecting production availability in the other cluster. We have some challenges with replicating base images \u2013 today we use the VMware Content Libraries to replicate the base across the two clusters, which does work but due to the de-prioritization of the traffic that vCenter imposes, it takes about 20 minutes to replicate base image changes from one cluster to the other. Recomposes must be done twice (on a \u201cper cluster\u201d basis), but this is not a big deal with Nutanix because they are so fast.

\n

\nI welcome any suggestions on how to get the base images from one side to the other in a more efficient way. We had some challenges when we used Nutanix Metro to replicate the VM across the clusters because we needed to create a snapshot from a single base image from within two separate VCenters and VMware did not like that. Anyways, I hope this helps others when they are pondering a fault tolerate Horizon View deployment on Nutanix.","quoteUsername":"jmancini","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好，



您提到了Metro，但是您是否尝试将模板VM放置在保护域中的主侧以复制到辅助站点来尝试异步复制？然后，您可以强制复制，查看何时完成并在第二个集群上旋转副本，用vCenter捕捉并重新组合。



其他选项将是一些手动复制过程，基于主机的复制。

\n

\nYou mentioned metro, but have you tried async replication by placing the template VM on primary side in a protection domain to be replicated to secondary site? You could then force replication, see when it finishes and spin out a copy on the 2nd cluster, snap it in vCenter and recompose.

\n

\nOther options would be some manual copy process, vSphere host based replication.","quoteUsername":"briansuhr","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我尚未尝试使用这种复制的保护域功能，但是，这是一个很好的建议。让我进行一些内部测试，看看情况如何。

我们有相同的设计用于2,000 CCU部署。效果很好。我不知道比Conent库更好。VMware应添加功能以具有中央金图像，您可以将其推到多个POD。

他们已经给了内容库做到这一点，但我认为重复应在存储层面上完成:)）
We have the same design for out 2,000 CCU deployment. Works well. I don't know of a better way than conent libraries. VMware should add a feature to have a central Gold image that you can push to multiple pods.<\/content-quote>

\n

\nThey already gave the Content Libraries to do that but i think the replicate should be done at the Storage level :))","quoteUsername":"andynta","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
